VQMITING KIER.

Application filed November 23, 1920. Serial No. 425,995.

To all whom'z't may concern:

Be it known that I soN, a citizenof the lInited States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Vomiting Kiers; and I do ereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in vomiting kiers and method of operating the same, and more particularly to an imrovement in injector operated vomiting iers.

The kiers of my prior Patents Nos. 775,450

' and 1,278,154, required ordinarily the maintenance of a liquor-line below the-top of the goods. Prior constructions of injector operated kiers required, for practical operation, the maintenance of a liquor level ab ove the top of the goods in order to prevent the exposure of the goods to the action of the live steam.

The object of the present invention is to provide an improved kier which may be successively operated at any desired liquor level.

The invention consists in the kier and method of bleaching hereinafter described and claimed:

In the drawings illustrating the preferred embodiment of the invention, Figure 1 is an elevation of the improved kier with a portion broken away, and Fig. 2 is a detail in elevation showing the mechanism for controlling the operation of the steam injector.

The preferred embodiment of the invention is described as follows. The kier proper consists of the usual sheet metal vessel 1 provided with a removable cover 2 secured y bolts in the usual manner at the top. The

materials to be treated are laid upon the usual grate 3 in the lower portion of the kier. A centrally located vomiting pipe extends upwardly from the bottom of the kier to near the top thereof and the liquor within the bottom of the kier is afforded access to the vomiting pipe through an elbow 14 secured to the tapered lower or-- tion of the vomiting pi e as shown in ig. 1. The liquor is elevate through the vomiting pipe 10 by a steam injector 16 of usual construction, the nozzle 17 of which extends into the lower portion of the vomiting pipe.

EUGENE D. Jn'rrnn- Steam is supplied to the injector through the steam pipe line 20 in which an automatically operated controlling valve is located at a convenientpoint nearthe upper portion of the kier.

Referring to Fig. 2, the valve 25 is provided with a stem extended upwardly through a stufiing box 31 in the valve casing 32. The upper end of the valve stem 30 is screwed into the bottom of a valve slide 38. The valve slide 38 is provided with a. timer gib 40 comprising a right angle piece of steel 41 secured thereto by stud bolts 42. The valve 25 is opened by the depression of the valve slide- 38 by means of a plurality of cam pins 44 which successively engage the timer gib 40. The cam pins 44 are mounted upon a timer wheel 46 continuously rotated at a relatively slow speed by an electric motor 28 through a reducing mechanism comprising Worms 49 and 50 and worm gears 51, and 52. The valve 25 is closed by the coil spring 45 a-fter'each cam pin 44 has passed from contact with the timer gib 40. The timer wheel 46 is mounted upon a counter shaft 48 journalel in arms 53 extended downwardly from a bracket 54 upon which the motor 28 is rigidly secured, The bracket 54 is supported in any convenient manner, preferably by be ing secured to a portion of the frame work of the building. The timer gib 40 may be adjusted in opposite directions to decrease and increase the duration of opening and closing of the valve 25. The upper end of the valve slide 38 is forked and embraces the counter shaft 48, the latter serving as a guide for the movements of the valve slide. In operation, the valve 25 is opened and closed by successive cam pins 44 to operate the steam injector and to thereby elevate, at predetermined intervals of time, small quantities of liquor through the vomiting pipe 10 from which the liquor is distributed by the spreader 58 over the top of .the goods.

The present kier has the following advantages over the kiers of my prior patents mentioned. The kier may be operated at any desired liquor level, thus enabling it to be used for all classes of work. The operation of the kier in short vomits, throwing a small quantity of liquor at frequent intervals upon the goods, contributes to the maintenance of a more uniform action of liquor upon the goods and also makes it possible to maintain a substantially constant liquor line at any desired level. The kier may be operated at relativel low steam pressure, for example, 15 poun s, thus eliminating the necessity of running a special steam line to the installation, as is sometimes required in the case of thekiers of my prior patents. Existing kiers may be converted to conform to the present invention, more economically than they may be converted to conform to said patents, and without the necessity of alteration of the pits.

The present kier also possesses the following advantages over the prior constructions of center vomit kiers. The necessity of operation at the relatively high liquor level is eliminated and any desired liquor level may be used. Furthermore, the intermittent operation of the steam injector contributes to the economy of the operation of the kier so that the kier may be operated upon much less steam than is required in the centervomit kiers, in many instances the saving of steam (and therefore of coal) being as much as from 70% to 90%. The present kier by keeping the level of the liquor always above the nozzle also completely eliminates the.danger of burning the goods by thus preventing live steam going over into the goods chamber so that it may be employed in those classes of operations for which the usual center vomit kiers were unsuited.

This invention may be embodied in both open and closed kiers.

While the preferred embodiment of the invention has been illustrated and described, it will be understood that the invention may be embodied in other forms within the scope of the following claims I claim: 1. A vomiting kier, havin in combination, a vessel for containing t e goods to be treated and the liquor for acting on the goods, 21. vomiting pipe connecting the top and bottom portions of the kier, a steam injector for operating the vomitin pipe to convey liquor from the bottom of t e kier to the top thereof, and an automatically,

operated valve for intermittently opening and closing the steam supply for the injector to vomit predetermined small quantities of liquor at frequent intervals on the top of the goods irrespective of whether the liquor level in the kier be high or low.

2. A vomiting kier having, in combination, a vessel containing the goods to be treated and the liquor for actin on the goods, a vomiting pipe connectin 516 top and bottom portions of the kier and being positioned entirely within the kier, a steam supply pipe extending through the bottom of the vessel and entering the lower end of the vomiting pipe to thereby form in connection with the lower end of the vomiting pipe a steam injector adapted to convey the liquor from the bottom of the kier to the top thereof, and an automatically-operated valve for intermittently opening and closing the steam supply pipe to thereby cause the injector to operate intermittently.

, 3. The method herein described of bleaching textile fabrics in a kier consisting in permitting the bleaching liquor to contlnuouslv percolate through the mass of goods, co lecting the percolated liquor in a chamber below the s, and returning the liquor to the top of the oods to be again percolated, the return of t e 1i uor being accomplished ,by an intermittent y-operating steam injector, the operations of the injector bein timed so as to always maintain a liquor leve above the injector-nozzle, so as to thereby avoid burning the goods by blowing livesteam thereon.
